Digestive Tumble is an innovative system that represents the functioning of the human digestive system. Through nine interlocking modules, the system provides information about the digestion of different foods to help users in making informed decisions about their dietary choices. Users interact with the system by inserting tokens representing their meal. These tokens transform into colourful beads, which traverse through the system at different rates depending upon the meal. For instance, since vegetables and fruits are quick to digest, the corresponding beads would traverse fast through the system whereas the beads corresponding to meat and dairy will follow slow digestion rates.

Digestive Tumble mimics the slowness involved in the digestion processes and presents the digestion of a meal over a long period. By doing so, the system aims to support slow reflection on our digestion processes. The tokens and beads support multimodal interactions (i.e., visual, tangible, and audio) with the system. The multimodality, slowness, and playfulness in interactions will allow deeper reflections on one’s dietary choices, encouraging users to adopt a diverse and balanced diet.
